We study two types of discrete operations on Coulomb branches of 3 d N $$ \mathcal{N} $$ = 4 quiver gauge theories using both abelianisation and the monopole formula. We generalise previous work on discrete quotients of Coulomb branches and introduce novel wreathed quiver theories. We further study quiver folding which produces Coulomb branches of non-simply laced quivers. Our methods explicitly describe Coulomb branches in terms of generators and relations including mass deformations.

箭袋折纸：离散测量和折叠

我们使用阿贝尔化和单极子公式研究了 3 d N $$ \mathcal{N} $$ = 4 quiver 规范理论的库仑分支上的两种类型的离散运算。我们概括了先前关于库仑分支离散商的工作，并介绍了新的花环箭袋理论。我们进一步研究了箭袋折叠，它产生了非简单花边箭袋的库仑分支。我们的方法根据生成器和关系（包括质量变形）明确描述了库仑分支。
